semen collection
for artificial insemination or laboratory evaluation or examination in a clinicopathological sense. Done by artificial vagina, electroejaculation, genital massage.
semen concentration
the number of spermatozoa per ml in the ejaculate.
semen diluent
there are a number of suitable diluents with some preference being given to one or other of them in each species. There are also different diluters for chilled liquid semen as distinct from frozen semen. Most diluters are based on biological fluids such as whole or skim milk, buttermilk, cream and egg yolk. The general cryoprotectant for freezing is glycerol. Called also semen extender.
semen extender
see semen diluent (above).
frozen semen
semen stored in liquid nitrogen at −196°C (−321°F).
semen non-sperm portion
see semen pre-sperm fraction (below).
semen pre-sperm fraction
the accessory gland fluid emitted at the beginning of ejaculation.
semen samples
part of an ejaculate collected for laboratory examination.
semen sperm-rich fraction
the portion of the ejaculate containing most of the spermatozoa.
semen stones
concretions of amorphous cellular debris and clumps of nuclear material found in seminal vesicles of bulls.
semen storage
chilled bull semen stored at 5°C can be stored and used for 5 days; frozen bull semen (−79°C using dry ice or −196°C using liquid nitrogen) can be stored and used successfully for up to 10 years, with only a small drop in fertility after 40 years.
